From efce79f09ae6daa77cd322df0d532beec3f445f5 Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Wed, 26 Mar 2008 13:40:36 +0000 Subject: Paul Brook writes: The attached patch adds support for compiling arm uClibc as pure Thumb code. This is needed because some recent ARM codes do not implement traditional ARM mode. Specifically: * Cortex-M1 - An extremely minimal FPGA based core that only implements Thumb-1 (aka ARMv6-M). * Cortex-M3 - A Thumb-2 only ARMv7-M core. Most of uClibc already builds in Thumb mode, all that is left are a handful of assembly bits. Tested on arm-uclinuxeabi. --- extra/Configs/Config.arm | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'extra/Configs') diff --git a/extra/Configs/Config.arm b/extra/Configs/Config.arm index 7aec08ce2..26e1f3da4 100644 --- a/extra/Configs/Config.arm +++ b/extra/Configs/Config.arm @@ -107,6 +107,16 @@ config CONFIG_ARM1176JZF_S bool "Arm 1176JZF-S" select ARCH_HAS_MMU +config CONFIG_ARM_CORTEX_M3 + bool "Arm Cortex-M3" + select ARCH_HAS_NO_MMU + select USE_BX + +config CONFIG_ARM_CORTEX_M1 + bool "Arm Cortex-M1" + select ARCH_HAS_NO_MMU + select USE_BX + config CONFIG_ARM_SA110 bool "Intel StrongArm SA-110" select ARCH_HAS_MMU -- cgit v1.2.3
